$-3\leq x$
$-7\leq\frac{7}{3}x\longrightarrow$ multiply both sides by $\frac{3}{7}$ $-7\times\frac{3}{7}\leq\frac{7}{3}x\times\frac{3}{7}\longrightarrow$ multiply $-3\leq x$ Check the endpoint $-7\overset?=\frac{7}{3}(-3)$ $-7=-7\checkmark$ Check the inequaity $-7\overset?\leq\frac{7}{3}(0)$ $-7\leq0\checkmark$ Since -3 is included in the solution, the endpoint on the graph is a solid circle.
